Antimony is a chemical element with diverse uses that falls into the range of critical raw material. Although it appears in nature as stibnite, mining this mineralogical species rare or uncommon, and basically recovered secondary material processing various elements (such gold copper). Another source for recovery recycling Sb-bearing wastes such batteries alloys. Once dissolved order to recover from different leachates, adsorption processes are ones seem have, at least scientific community, highest acceptance. This work reviews most recent advances (in 2024) antimony sources using not only but also other technologies practical interest.

Cadmium (Cd) and antimony (Sb) coexistence in industrial effluents poses significant threats to environmental safety human health. Consequently, developing effective methods for the simultaneous removal of Cd(II) Sb(V) from aqueous solutions is critically important. In this study, adsorption performance a birnessite (BS) fulvic acid (FA) composite (BS-FA) was optimized using response surface methodology (RSM) combination with machine learning (ML) techniques, including genetic algorithm-back propagation neural network (GABP) random forest (RF) models. The RF model demonstrated superior predictive accuracy (R² = 0.8037, RMSE 0.0625) compared RSM GABP Under conditions (pH 6, adsorbent dosage 0.87 g L- 1, time 4 h, ionic strength 0.01 mol L⁻¹, initial concentration 25.5 mg L⁻¹), efficiencies were 96.9% 70.2%, respectively. Microscopic mechanistic analyses revealed that interacted Mn-O bonds BS oxygen-containing functional groups (C-OH -COOH) FA, forming stable complexes within Cd-Sb system. This study successfully integrates ML models optimize predict process, offering valuable insights mitigating health risks associated Cd Sb contamination water treatment.
